HARTFORD, CONNECTICUT, A CORPORATION 0F RADIATOR FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Mar. 2a, reto.

Application led July 16, 1904. Serial No. 21'6,785.

To all @l2/0m 'it may concern.'

Be it known that I, LoUrs I-I. BRINKMAN, a citizen of the United States,residing at West Hartford, in the county of Hartford and State ofConnecticut, have invented a new and useful Improvement in Radiators forMotor-Vehicles, of which the following is a specification, accompaniedby drawings forming a part of the same, in which- Figure 1 represents aside view of my improved radiator as applied to a motor vehicle. Fig. 2is a front view of the same. Fig. 3 is a vertical sectional view of aportion of the radiator shown on line 3-3, Fig. 2. Fig. 4 is a verticalsectional view on a plane at right angles to that shown in Fig. 3, andFig. 5 isa perspective view of a detached portion of the water pipes.

Similar reference letters and figures refer to similar parts in thedifferent views.

My present invention has for its object to reduce the cost and toincrease the durability and efficiency of that class of radiators whichare employed in motor vehicles as a part of a water circulating systemfor the purpose of cooling the cylinders of explosive engines, and itconsists in the construction and arrangement of parts as hereinafterdescribed, the novel features being pointed out in the annexed claims.

Referring to the accompanying drawings, 1 denotes the hood or bonnet ofa motor vehicle, 2 a portion of the chassis, `3 the front wheels, and 4a wat-er cooling radiator' em bodying my invention, having an opening inthe top closed by a cap 5 for the purpose of filling the radiator withwater. The radiator 4 comprises an upper water chamber 6 and a lowerwater chamber 7, said chambers being connected with the jacketed spacearound the engine cylinder in the usual and wellknown manner inradiators of this class. The upper chamber 6 and the lower chamber 7 areconnected together by serpentine water pipes 8 having their upper endsconnected at 9 with the upper water chamber 6, and their lower endsconnected at 10-with the lower water chamber 7.

The water pipes 8 are preferably arranged in a series of horizontalsections 11 connected by return bends 12, 12, and forming continuouspassages 13, 13, by which water may flow from the chamber 6 downwardlyThe plates 14 and 15 are preferably pinched together at 18 to divide theinclosed space between the plates 14 and 15 into three separate waterpassages 13, Fig; 3. Each of the plates 14 and 15 before being united,are stamped by suitable unches and dies to form the raised protu erances19 in order to increase the radiating surfaces of the plates. Thehorizontal sections 11 of the pipes 8 are separated by corrugatedradiating plates 20. The corrugations of the plates 20 are alternatelyattached at 21 to the surfaces of the water pipes 8 so that the heatgiven to the water pipes by the circulating hot water within thepassages 13 will be imparted to the corrugated radiating plates'20.

The water chambers 6 and 7 are preferably connected at each end of theradiator by plates 22, Fig. 4, forming an inclosing case for the ends,but the front and rear sides are left entirely open to form unobstructedair passages between the pipes 8 and the convolutions of the corrugatedplates 20, through which currents of cooling air are caused to pass bythe motion of the motor car or by other suitable means, such as a rotaryfan, commonly employed with radiating devices of this class.

The corrugated plates 20 and the pipes S are preferably formed from thinsheets of copper, brass, or other metal capable of a rapid radiation ofheat, and the employment of the corrugated plates 2() increases theamount of metallic surface brought in contact with the cooling currentsof air,

-t-hereby adding to the cooling eticiency of the apparatus. An opening23 is provided in the chamber 6 through which water is received from theengine cylinder and an opening 24 is provided in the lower chamber 7through which water is returned to the cylinders, the circulationbetween the chambers 6 and 7 being maintained either by the dierence inspecific gravityA between the heated and partially `cooled Water or bymeans of a pump as is usually employed in radiators of this class.

The water pipes 8 are Iiattened on their upper and lower surfaces torestrict the inclosed water passages 13, so that the current of water isobligedV to flow in close proximity tothe Hattened sides of the waterpipes and also to form surfaces in which the raised protuberances 19maybe formed. The flattened sides'of the water pipes and the surfaces ofthe corrugated plates 20, form air fines through the structure,

through which cooling currents of air pass.-

What I claim as my invention and desire to secure by Letters Patent isl. In an apparatus of the class described, y

the combination of a flattened water pipe formed of parallel plates withlongitudinal depressions in each plate in contact, and with the edges ofeach plate bent at righ angles and fastened together.

2. In an apparatus of the class described, horizontal chambers, aflattened water pipe connecting, said chambers, said pipe comprisinghorizontal sections and reverse bends and formed from two platesparallel throughout the length of the pipe, with longitudinaldepressions in each platev in contact throughout each horizontal sectionand with the edges of each plate bent atv right angles and fastenedtogether.

3. In an apparatus of the class described, horizontal chambers, aattened water pipe connecting said chambers, com risin horizontalsections and reverse ben s and ormedv of parallel lates, each platehaving opposite longitudinal depressions in each' section in contact toincrease the radiating surface of said pipeeac'h plate alsol providedwith protuberances arranged between said depressions, and a ,corrugatedplate between said horizontal sections arranged to contact with saidpipebetween said protuberances and transverse to said depressions.

4. In an apparatus of the class described, horizontalchambers, aflattened water pipe connecting said chambers, com rising horizontalsections and reverse ben s and formed from two plates vparallelthroughout the length of the pipe, having in said horizontal sectionsopposite longitudinal depressions in. each plate, with the bottoms of.said opposite depressions parallel and in contact, and a corrugatedplate between said sections in contact'` with said pipe transverse tosaid depressions.
